The search literature offers several mechanisms by which a multiproduct retailer's offering of a larger variety affects consumers' search behavior and hence prices. Among them are (1) higher sales to be generated when lower prices discourage consumers' further search; and (2) more pricing power...

This paper develops and analyzes a model of international trade comprising multiproduct firms that can produce a range of product varieties distinguished by quality. First, it analyses the within-firm distribution of product quality and argues that firms export decisions are sensitive to their...

This paper investigates the effects of mergers on the product mix of multiproduct firms. Thus, we open the black box of post-merger efficiency improvements to reveal a new margin of adjustment along the product dimension. We analyze horizontal mergers in a theoretical model where oligopolistic...

We analyze endogenous choice of organizational forms between U-form and M-form in the multiproduct mixed duopoly. With managerial delegation in public and private firms, we find that choosing M-form for the public and private firms is a dominant strategy under mixed duopoly in either Bertrand or...

The goal of this paper is to study the role of multi-product firms in the market provision of product variety. The analysis is conducted using the spokes model of non-localized competition proposed by Chen and Riordan (2007). Firstly, we show that multi-product firms are at a competitive...

This research sheds light on the role of product scope on the innovation activity of multinational multi-product firms. We use patent citation data to break down innovation into two types by measuring the degree to which innovation performed by firms is fundamental and the extent to which the...

This paper develops a general equilibrium model of multi-product firms and analyzes their behavior during trade liberalization. Firm productivity in a given product is modeled as a combination of firm-level "ability" and firm-product-level "expertise", both of which are stochastic and unknown...

We document how demand shocks in export markets lead French multi-product exporters to re-allocate the mix of products sold in those destinations. In response to positive demand shocks, those French firms skew their export sales towards their best performing products; and also extend the range...
